KPeh said:Lawrence of Arabia and Bladerunner. Honourable mention to The Killing Fields and Doctor Zhivago though.
Seeing Lawrence of Arabia (restored) on 70mm at a cinema a few weeks ago was quite quite extraordinary. The DVD quality is pathetic in comparison. I think those two films are head over heels above the rest for a combination of story, acting, atmosphere, cinematography and soundtrack. And they're not shallow films. Both attaining pretty much perfection in my book.
Where did you see the restored version. I'd like to see that myself.
